PRODUCTIVITY OF CHICKPEA DEPENDINDING OF SOWING DATE AND SOWING SCHEME IN THE FOOTHILL ZONE OF CHUI VALLEY
In Kyrgyzstan, for the period from 1990 to 2014 nineteen times increased grain and legume areas and in 2014 they compose 61 000 ha, this was mainly due to the growth and expansion of areas of beans chickpea crop in the northern part of the country. Meanwhile, there are no scientific based recommendations for the cultivation of chickpea. Has been studied productivity of chickpea varieties Kyrgyzskii Mestnyi and Yulduz sowing dates on May 1, May 15 and June 1 in the grey-brownish soil in northern Chui valley of the Kyrgyz Republic. In each time of sowing, optimum scheme was 45x15 cm. Delay of sowing dates for 15 days significantly reduces the productivity of chickpea crops. More sensitive for factor of sowing dates was variety Kyrgyz local in sowing schemes 60x15 cm and 45x15 cm. Delay of sowing a one-month also significantly decrease productivity of variety Kyrgyzskii Mestnyi. Delaying of the sowing period from 15 to 30 days variety Yulduz has been respond poorly than variety Kyrgyzskii Mestnyi. Our own analysis of variance for the yielding data showed that sowing date (factor A 56,2-68,8%) and then sowing schemes (factor B 22,5-34,8%) significantly hade strong impact for the grain yielding in variety Kyrgyzskii Mestnyi. There was also noticed strong effect in sowing date (48,4-72,2%) and less in planting scheme (19,8-34,0%) in variety Yulduz. The synergy of two factors in both varieties was also different. On the average during three years the interaction of factors in variety Kyrgyzskii Mestnyi - 6,24%, in variety Yulduz - 4,0%.
